Hello! 👋 I am a Senior Software Engineer at Luma AI, building data infra for large-scale multimodal training. Before joining Luma, I worked on infra data plane for Ray at Anyscale and ML storage disaggregation at Meta.

My doctoral research at UC Santa Cruz focused on distributed storage systems, cloud computing, and quality of service. I earned my Ph.D. in Computer Engineering in 2025, co-advised by Prof. Heiner Litz and Prof. Chen Qian (supported by CRSS & NSF).

My current interests focus on building and scaling infra for:

• Long-context memory
• Long-horizon agent systems
• Continual learning

I received my B.E. in Computer Science (with honors) from Sichuan University in 2018, and was selected as a Computer Science Star.
